A hands-on walkthrough of refactoring an existing Angular form (originally built with Template Driven Forms) to use Angular's new experimental Signal Forms feature, introduced in Angular 21. Covers creating the form with the `form` function from `@angular/forms/signals`, binding fields in templates using the `Field` directive, defining validation rules, managing field states (touched, dirty, disabled, hidden), building reusable nested group components with the `schema` function, and handling async form submission. The author notes key differences from existing form approaches — such as validators being added as HTML attributes, auto-generated field names, and the absence of `ng-` CSS classes — and concludes that Signal Forms' declarative conditional logic and TypeScript-centric definition make it a compelling replacement for both Template Driven and Reactive Forms.
